  1. 11. Adaptive air-fuel ratio control for combustion engines

    University essay from Institutionen för systemteknik

    Author : Eva Lundin; [2010]
    Keywords : ;

    Abstract : Around the world, vehicle emission regulations become stricter, increasing exhaust emission demands. To manage these rules and regulations, vehicle manufacturers put a lot of effort into minimizing the exhaust emissions. The three-way catalytic converter was developed, and today it is the most commonly used device to control the exhaust emissions. READ MORE

  3. 12. PERFORMANCE EVALUATION OF MPLS/GMPLS CONTROL PLANE SIGNALING PROTOCOLS

    University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Author : Freelance Bwalya and Lawrence Ngugi; [2009]
    Keywords : MPLS; GMPLS; RSVP-TE; CR-LDP; QoS;

    Abstract : Multi-Protocol Label Switching (MPLS) emerged as a suitable solution to optimization of Internet Protocol (IP) networks. It improves network efficiency, utilization of resources and resilience in packet switched networks. With MPLS, packet forwarding decisions are made based on label inspection rather than packet header information. READ MORE

  4. 13. Model-based Air and Fuel Path Control of a VCR Engine

    University essay from Institutionen för systemteknik

    Author : Tobias Lindell; [2009]
    Keywords : engine control; volumetric efficiency modeling; throttle control; lambda control;

    Abstract : The objective of the work was to develop a basic control system for an advancedexperimental engine from scratch. The engine this work revolves around is a Saabvariable compression engine.A new control system is developed based on the naked engine, stripped of theoriginal control system. READ MORE

  5. 14. Investigation of Correlations Between COV of Ion Integral and COV of IMEP in a Port-Injected Natural-Gas Engine

    University essay from Institutionen för systemteknik

    Author : Johan Molin; [2008]
    Keywords : COV; IMEP; Ion current; EGR;

    Abstract : Correlations between the coefficient of variations (COV) of ion current integrals and COV of indicated mean effective pressure (IMEP) are investigated. The investigations are made to see if there is a possibility to use ion sense technique for closed loop combustion control to maximize Exhaust Gas Recirculation (EGR) level with remaining combustion stability.

  6. 15. On optimal control of the wastegate in a turbocharged SI engine

    University essay from KTH/Reglerteknik

    Author : Roberto Argolini; Viviana Bloisi; [2007]
    Keywords : ;

    Abstract : The project aims to improve positive torque transient response through more advanced wastegate controllers than what are used today. All controllers are developed for a standard General Motors turbocharged engine. In many turbocharged SI engines, a wastegate is used for preventing the turbine to overrun and to decrease the pumping loss. READ MORE
